I've been using GFO from BRS for awhile and have no complaints. Keeps phosphates in check very effectively. I always recommend GFO to anyone having phosphate issues.

I absolutely can't do without the BRS bulk GFO. It drastically improved the water quality of all of my aquariums. A 180gal reef tank and a 110gal fish only. Phosphate levels are almost not existent now after using the GFO, especially in the dual GFO and carbon media reactor.

Easy to use, have used different brands of GFO in the past. After adding BRS GFO, algae problems have reduced to nothing!

Ordered up some of this gfo.. Samre as the carbon seems to be doing a good job so far. Also did not notice much waste when rinsing it off.. huge deal for me when your looking at gfo prices..

GREAT PRODUCT AT A GREAT PRICE!!!By Dolmo5000on 6/25/2013

BRS does it again! I have looked far and wide for GFO at a cheaper price. Although there are a very few places advertising it for a cheaper price reviews of the product say it contains lots and lots of dust. I believe that BRS sells a fantastic product and will purchase GFO and all other bulk additive from them as long as I'm in the hobby (rest of my life). GREAT JOB BRS!!!
